Description

Geophagus sveni
Geophagus sveni, commonly known as Sven’s Geophagus, is a captivating species of freshwater fish belonging to the Cichlidae family. Native to the rivers and floodplains of the Amazon Basin, particularly in Brazil, this fish is prized for its stunning appearance and unique behavior, making it a favorite among aquarists.
Appearance
Sven’s Geophagus is characterized by its elongated, oval-shaped body, which can grow to about 6 to 8 inches (15 to 20 cm) in length. They typically display a striking color palette, with a base color ranging from light brown to yellowish, adorned with beautiful iridescent spots and bands. Males are often more vibrantly colored than females, particularly during breeding periods, and can exhibit pronounced nuchal humps.
Habitat and Behavior
In the wild, Geophagus sveni inhabits shallow, sandy-bottomed rivers and floodplain habitats. They are known for their unique feeding behavior, often sifting through the substrate to find food, which includes small invertebrates and plant matter. This substrate-sifting behavior not only aids in their foraging but also helps maintain the ecological balance of their habitat.
Diet
Sven’s Geophagus are omnivorous and thrive on a varied diet. In captivity, they should be provided with high-quality pellets, frozen or live foods like bloodworms and brine shrimp, as well as blanched vegetables such as zucchini and spinach. This varied diet helps enhance their coloration and overall health.
Tank Requirements
To accommodate Geophagus sveni, a minimum tank size of 55 gallons is recommended, as they require ample swimming space and hiding spots. They prefer slightly acidic to neutral water conditions, with a pH range of 6.0 to 7.5 and a temperature between 74°F and 82°F (23°C to 28°C). Providing a sandy substrate is ideal for mimicking their natural habitat and allowing them to exhibit their natural behavior.
Compatibility
Sven’s Geophagus is generally peaceful but can display territorial behavior, especially during breeding. They can be housed with a variety of community fish, including larger tetras, cichlids, and other non-aggressive species. It is advisable to avoid keeping them with very small fish that may be seen as food or with overly aggressive species.
Conclusion
Geophagus sveni is a stunning and engaging addition to any freshwater aquarium, offering both beauty and fascinating behaviors. With proper care, a suitable environment, and a balanced diet, these cichlids can thrive, enhancing the overall appeal of your aquatic setup. Their unique substrate-sifting behavior and vibrant coloration make them a favorite among both novice and experienced aquarists alike.
